xStack DGS-3400 Series Fast Ethernet Switch
Parameter Description
Profile ID (1-5) Type in a unique identifier number for this profile set. This value can be set from 1 -
5.
Type Select profile based on Ethernet (MAC Address), IP address or Packet Content
Mask. This will change the menu according to the requirements for the type of
profile.
Select
Ethernet to instruct the Switch to examine the layer 2 part of each packet
header.
Select
IP to instruct the Switch to examine the IP address in each frame's header.
Select Packet Content Mask to specify a mask to hide the content of the packet
header.
VLAN Selecting this option instructs the Switch to examine the VLAN part of each packet
header and use this as the, or part of the criterion for forwarding.
Source IP Mask Enter an IP address mask for the source IP address.
Destination IP Mask Enter an IP address mask for the destination IP address.
DSCP Selecting this option instructs the Switch to examine the DiffServ Code part of each
packet header and use this as the, or part of the criterion for forwarding.
Protocol
Selecting this option instructs the Switch to examine the protocol type value in each
frame's header. You must then specify what protocol(s) to include according to the
following guidelines:
Select ICMP to instruct the Switch to examine the Internet Control Message
Protocol (ICMP) field in each frame's header.
Select Type to further specify that the access profile will apply an ICMP type value,
or specify Code to further specify that the access profile will apply an ICMP code
value.
Select IGMP to instruct the Switch to examine the Internet Group Management
Protocol (IGMP) field in each frame's header.
Select Type to further specify that the access profile will apply an IGMP type value
Select TCP to use the TCP port number contained in an incoming packet as the
forwarding criterion. Selecting TCP requires that you specify a source port mask
and/or a destination port mask. The user may also identify which flag bits to filter.
Flag bits are parts of a packet that determine what to do with the packet. The user
may filter packets by filtering certain flag bits within the packets, by checking the
boxes corresponding to the flag bits of the TCP field. The user may choose
between urg (urgent), ack (acknowledgement), psh (push), rst (reset), syn
(synchronize), fin (finish).
src port mask - Specify a TCP port mask for the source port in hex form (hex 0x0-
0xffff), which you wish to filter.
dest port mask - Specify a TCP port mask for the destination port in hex form (hex
0x0-0xffff) which you wish to filter.
Select UDP to use the UDP port number contained in an incoming packet as the
forwarding criterion. Selecting UDP requires that you specify a source port mask
and/or a destination port mask.
src port mask - Specify a TCP port mask for the source port in hex form (hex 0x0-
0xffff).
dest port mask - Specify a TCP port mask for the destination port in hex form (hex
0x0-0xffff).
protocol id - Enter a value defining the protocol ID in the packet header to mask.
Specify the protocol ID mask in hex form (hex 0x0-0xffffffff).
